What is Sulfr hexafluoride Gas? | GasQuip - Sulfr hexafluoride Equipment and Training

What this means is that as an arc is formed, it is quickly quenched by the gaz sf6 Gas. The actual gaz sf6 gas itself is ripped apart by the immense amount of energy passing through it, but much like wolverine (or deadpool, spiderman etc.), the gas heals itself and recombines at the atomic level. Unfortunately, other byproducts can also be formed like water and sulfur dioxide, which causes problems for the longevity of electrical components.Get price
